• #### Two mod-p Johnson filtrations ﻿

(2014-04-17)
We consider two mod-p central series of the free group given by Stallings and Zassenhaus. Applying these series to definitions of Dennis Johnson's filtration of the mapping class group we obtain two mod-p Johnson filtrations. ...
• #### TWO MODELS FOR ISOTOPIC VARIATIONS IN THE LUNAR REGOLITH ﻿

(1980)
Two independent models are presented which attempt to account for large, apparently secular, isotopic variations recorded in lunar samples. To explain the observed long-term increase of ('15)N/('14)N, the first model ...

(1973)
• #### Two new town processes ﻿

(1971)
The philosophy behind new town building in the U.S. and Britain is basically a common philosophy. The commonality stems from the common origin of the idea, and the cross-relationship of experience between the two countries. ...
• #### Two nucleon stripping reactions and the role of the tensor force ﻿

(1962)
In recent years an increasing number of nuclear reactions have been studied experimentally in which more then one nucleon is transferred from the bombarding particle to the target nucleus. The reactions studied are primarily ...
• #### Two paths to command: command systems of the Union and the Confederacy, 1861-1865 ﻿

(1979)
A parallel look at the command systems of the Union and the Confederacy as they evolved during the Civil War in part explains why the war was fought the way it was and why it lasted four years. Both nations began the war ...
• #### Two photon parametric conversion of Moessbauer gamma rays ﻿

(1975)
This thesis considers aspects of parametric conversion of Mossbauer gamma rays. This process is important because it could be used to tune the output of a gamma ray laser; but, furthermore, it is a process of fundamental ...

(1978)
• #### Two Stage Repair of Composite Craniofacial Defects with Antibiotic Releasing Porous Poly(methyl methacrylate) Space Maintainers and Bone Regeneration ﻿

(2013-09-16)
Craniofacial defects resulting from trauma and resection present many challenges to reconstruction due to the complex structure, combinations of tissues, and environment, with exposure to the oral, skin and nasal mucosal ...
• #### Two Studies from the Development Cycle ofMacroscopic Carbon Nanotube Materials: Rheology of Carbon Nanotubes in Superacids and Characterization of the Electrochemical Circuit Behavior of Carbon Nanotube Fiber Electrodes for Electrophysiology ﻿

(2017-04-21)
Carbon nanotubes (CNTs) possess a variety of properties which make them attractive as building blocks for high performance multi-functional materials. The discovery that superacids such as chlorosulfonic acid (ClHSO3) act ...
• #### Two symphonic movements ﻿

(1985)
Two Symphonic Movements is an orchestral work dealing with the concepts of growth, contrast, and symmetry. Each thematic presentation in the work allows the two major motivic ideas to interact and evolve in such a way that ...
• #### Two Variants on the Plateau Problem ﻿

(2016-03-11)
The Plateau problem in $\mbb{R}^3$ begins with a given simple, closed curve $\gamma$, and asks to find a surface $M$ with $\partial M= \gamma$ that minimizes area among all surfaces with $\gamma$ as their boundary. In ...
• #### Two-dimensional asymptotic equilibrium representations of three-dimensional magnetospheric models ﻿

(1992)
The Harris (1962) model, which is consistent with local thermodynamic equilibrium (LTE) does not represent the earth's magnetotail, which has a magnetic field component normal to the equatorial plane. However, inclusion ...
• #### Two-dimensional modeling of flow and sedimentation ﻿

(1993)
A two-dimensional (vertical) flow model is developed to simulate open channel flow. The governing equations are solved without any depth averaging. Free surface movement is handled with the help of Arbitrary Lagrangian ...

(1967)
• #### Two-generator binary convolutional codes ﻿

(1966)
In this research, a stage by stage optimization of the spectra of two-generator binary convolutional codes was carried out. Properties of the code tree were used to minimize the computations required in the search. The ...
• #### Two-stage ARMA spectral and bispectral modeling with application to space shuttle flight data ﻿

(1993)
Parametric models for the representation of the power spectrum and bispectrum of a bank of data by the use of a two-stage, auto/cross-correlation matching (ACM) technique are developed. First, the applicability of the ACM ...
• #### Type and craft in the production of architecture (Texas) ﻿

(1993)
Type and craftsmanship are closely bound in an architecture of urban density. Craftsmanship, manipulating material and understanding material culture provides an essential base for knowledge that can guide the design ...
• #### Type II dihydrofolate reductases: Probing the natural diversity of enzyme active sites ﻿

(1992)
Type II dihydrofolate reductases (DHFRs) encoded by the R67 and R388 plasmids are sequence and structurally different from known chromosomal DHFRs, and are responsible for conferring trimethoprim resistance to the host ...
• #### Type-based specialization in a telescoping compiler for Matlab ﻿

(2003)
This thesis develops telescoping-language technology for automatically generating high performance libraries from development code written in high-level languages, like Matlab. The generated library subroutines have ...
